First rebuild

So I have a 1986 cj-7 and am trying to do a rebuild on it every one else is telling me clean it up and sell to let it be someone else's problem but that's just not an option for me. So I'm just looking for a guide through it and tips and tricks and any money savers are BIG PLUS. Any help is appreciated.

The first thing I'd do is address the coolant leak in cylinder 6.

HI .. I don't think he has a coolant leak the one plug is newer and different than the rest. looks like its not very bad..I can't see all 6 of the plugs but the plugs I see need changed very badly except the one newer auto lite plug.. the rest are Champion. The plugs just look sooty not wet with oil or anything Just in need of changing.. Can't tell what carb is on there.. I can see a header so someone may have put to big of a carb on it, It kind of looks like a 2100 Motor Craft, also the plugs look rich (being black sooty) from to much carb. Might need to re-jet the carb.
good luck

The clean plug is also a platinum. The rest are copper.

Looks like a good project base, to me. It already has an aluminum valve cover and the large distributor cap. Someone started making upgrades.

Earth first... We'll Jeep the other planets later.

The PCV plumbing is screwed up, and I don't see a return line on fuel system, which could be the reason for the rich fuel condition.

OP, this is a good site to learn about your engine. I also suggest searching for a free download of the Factory Service Manual for your Jeep.

Those two resources should answer the majority of your questions.

Wow I didn't see that PCV mess up.. OP. the PCV connection at the back of the motor need to go to the air filter or have a filter element on it. It is for fresh air INTO the motor so the PCV valve at the front of the motor can pull out the fumes and such. It is NOT suppose to be hooked together. That alone can cause excess pressure inside the motor and cause gasket blow outs.
OH the other end of the PCV is suppose to go to the charcoal canister which might be missing..
good luck
